Because soon after the earth formed, when it was still hot and mostly molten, the materials separated themselves out. Most of the denser materials, like nickel and iron, sunk towards the center (being the core) and the lighter materials floated to the surface (the crust). So due to the separation the crust composition is different than the core.

How do you find the earth's crust compared to the other lyers?
Earth's crust is the thinnest among the other earth's layers.
How does the density of Earth's crust compare to the other layers?
The crust is the least dense of the Earth's layers. Each layer is denser than the layer above it. This is very logical, since lighter layers float on top of heavier layers.
What are the hardest to softest layers of earth?
the hardest layer of the earth's surface is the crust because it is made up of rocks and other hard materials
What is a interesting fact about the earth's crust?
1. The earth outermost surface is called crust. 2.The crust is about 25m. thick beneath the continents. 3.The crust is relatively light and brittle. 4.Most earthquakes occur within in the crust.
Describe earths crust?
The Earth's outermost layer of hard brittle rock is called the crust. The crust is typically about 23 miles thick beneath continents, and about 6.5 miles thick beneath oceans. The crust is relatively light and brittle compared to other Earth layers. Most earthquakes occur within the crust.
How do you find the earth's crust compared to the other lyers?
Earth's crust is the thinnest among the other earth's layers.
When compared to the other layers of Earth which layer has the lowest density?
The Crust
How does the density of Earth's crust compare to the other layers?
The crust is the least dense of the Earth's layers. Each layer is denser than the layer above it. This is very logical, since lighter layers float on top of heavier layers.
What layer of the earth is where we get our resources?
The crust. We have not been able to access the other layers.
Are the layers of earth farthest from the crust the newest and youngest layers?
Yes because like sedimentary rocks they stacked on top of each other
Is the crust the most expansive layer of earth?
The interior of Earth, similar to the other terrestrial planets, is chemically divided into layers. The mantle is a layer between the crust and the outer core.
What are the similarities between the mantle and the crust?
They are both layers of the Earth comprised of rock....other than that, there are no similarities.
In which layer of earth would you expect to find the least dense materials?
The crust is the least dense portion of the solid Earth because it is the thinnest layer.
What are the hardest to softest layers of earth?
the hardest layer of the earth's surface is the crust because it is made up of rocks and other hard materials
Layers of crust?
the earth's crust is a thin layer about, the crust can be more than 80km thick in some parts and less than 1 km thick in other parts. it is the ground that we live on
The crust and lithosphere are the outermost layers of the earth and?
consist of large sections called tectonic plates, which move relative to each other.
What are the limitations of scientist model about the earth layers?
Well it is much smaller than the actual earth. The crust is a little tiny tiny sliver compared to the other layers. It doesn't get to show the temperature or state of matter on a model (at least most).
